Diesel School Bus Retrofits

The Massachusetts Department of Environmental Protection's MASSCLEANDIESEL: Clean Air for Kids program announced that it has recently retrofitted 302 additional school buses with diesel pollution controls in 67 communities in the state. The program has retrofitted over 1,400 buses in 283 municipalities in Massachusetts. The retrofits, funded by the state with money related to the Big Dig, are done at no cost to the bus owners. The retrofits remove carbon monoxide, particulates, and hydrocarbons from the tailpipe emissions. Particulates can contribute to heart problems and cause bronchitis and asthma. Hydrocarbons are a factor in smog formation, and carbon monoxide reduces oxygen delivery in the body.
